I have a lot of questions: 5 hrs * 3 jobs = 15 hours. If you want a net pay of $1000 per week, you need to be paid in excess of $65 per hour, more like $80+ per hour.
Yes it's possible. Likely not though for you.
In theoretically yes, in reality very doubtful.
Yes, just do the math .
Why would you split your efforts between three jobs only working five hours??? What kind of work/how much do you earn? I earn $37 an hour, so working 15 hours wiould earn $555 a week, in ten weeks, that would be 5,550 BEFORE TAXES AND DEDUCTIONS.
YOU ARE NOT ABLE TO DO THE MATH YOURSELF ???????
